Is rot13 really considered encryption? If so here are some shell functions to go with this.
function rot13()
{
if [ -r $1 ]; then cat $1 | tr '[N-ZA-Mn-za-m5-90-4]' '[A-Za-z0-9]'; else echo $* | tr '[N-ZA-Mn-za-m5-90-4]' '[A-Za-z0-9]'; fi
}
function rot47()
{
if [ -r $1 ]; then cat $1 | tr '\!-~' 'P-~\!-O' ; else echo $* | tr '\!-~' 'P-~\!-O'; fi
}
Example:
echo 'Guvf vf zl fhcre frperg grkg. Ab bar pna ernq vg. Abg rira Pnrfre uvzfrys! Vs lbh jnag gb haqrefgnaq ubj guvf vaperqvoyl fgebat naq sbbycebbs rapelcgvba jbexf, cyrnfr ernq zl oybt.' | rot13
